  1. (39 other versions)في البدء كان سطر الأوامر.Salah Osman - manuscript
    هل فوجئت يومًا بأن نظام التشغيل لهاتفك أو حاسوبك لا يقبل التحديث لأن الشركة المُنتجة قد أوقفت دعم إصدارٍ ما زال يعمل، لكي تحث عملائها على شراء إصدار جديد أكثر كفاءة وأشد جذبًا وإشباعًا لحاجات المستخدمين؟ وهل تساءلت يومًا عن طبيعة العلاقة التي تربط بينك وبين هاتفك أو حاسوبك أو أي جهازٍ إلكتروني آخر تمتلكه، هل هي علاقة عاطفية قوامها المظهر والتباهي أم علاقة عقلانية قوامها الحاجة ونمط الاستخدام؟ وهل فكرت يومًا في كيفية عمل هاتفك أو حاسوبك، وما الذي يحدث (...)

  2. Deductive Computing over Knowledge Bases: Prolog and Datalog.Luis M. Augusto - 2024 - Journal of Knowledge Structures and Systems 5 (1):1-62.
    Knowledge representation (KR) is actually more than representation: It involves also inference, namely inference of “new” knowledge, i.e. new facts. Logic programming is a suitable KR medium, but more often than not discussions on this programming paradigm focus on aspects other than KR. In this paper, I elaborate on the general theory of logic programming and give the essentials of two of its main implementations, to wit, Prolog and Datalog, from the viewpoint of deductive computing over knowledge bases, which includes (...)

  3. Two-level grammars: Some interesting properties of van Wijngaarden grammars.Luis M. Augusto - 2023 - Omega - Journal of Formal Languages 1:3-34.
    The van Wijngaarden grammars are two-level grammars that present many interesting properties. In the present article I elaborate on six of these properties, to wit, (i) their being constituted by two grammars, (ii) their ability to generate (possibly infinitely many) strict languages and their own metalanguage, (iii) their context-sensitivity, (iv) their high descriptive power, (v) their productivity, or the ability to generate an infinite number of production rules, and (vi) their equivalence with the unrestricted, or Type-0, Chomsky grammars.

  4. The van Wijngaarden grammars: A syntax primer with decidable restrictions.Luis M. Augusto - 2023 - Journal of Knowledge Structures and Systems 4 (2):1-39.
    Expressiveness and decidability are two core aspects of programming languages that should be thoroughly known by those who use them; this includes knowledge of their metalanguages a.k.a. formal grammars. The van Wijngaarden grammars (WGs) are capable of generating all the languages in the Chomsky hierarchy and beyond; this makes them a relevant tool in the design of (more) expressive programming languages. But this expressiveness comes at a very high cost: The syntax of WGs is extremely complex and the decision problem (...)

  5. Note on the complexities of simple things such as a timeline. On the notions text, e-text, hypertext, and origins of machine translation.Niels Ole Finnemann - 2021 - In Frode Hegland (ed.), The Future of Text, vol. 2. Liquid Text. pp. pp 149-156..
    The composition of a timeline depends on purpose, perspective, and scale – and of the very understanding of the word, the phenomenon referred to, and whether the focus is the idea or concept, an instance of an idea or a phenomenon, a process, or an event and so forth. The main function of timelines is to provide an overview over a long history, it is a kind of a mnemotechnic device or a particular kind of Knowledge Organization System (KOS).b The (...)

  6. A Shift from Cloud Computing Model to Fog Computing.C. Sailesh & S. Svermani - 2016 - Journal of Applied Computing 1 (1).
    Cloud computing has provided many opportunities to businesses and individuals. It enables global and on demand network access to a shared pool of resources with minimal management effort. However, this bliss has become a problem for latency-sensitive applications. To improve efficiency of cloud and to reduce the amount of data that needs to be transported to the cloud for data processing, analysis and storage, a new network architect technology 'Fog Computing' has been introduced. In fog computing, small applications and resources (...)
